41 <para>
42 <function>gluErrorString</function> produces an error string from a GL or GLU error code. The string
43 is in ISO Latin 1 format. For example,
44 <function>gluErrorString</function>(<constant>GLU_OUT_OF_MEMORY</constant>) returns the string
45 <emphasis>out of memory</emphasis>.
46 </para>
47 <para>
48 The standard GLU error codes are <constant>GLU_INVALID_ENUM</constant>,
49 <constant>GLU_INVALID_VALUE</constant>,
50 and <constant>GLU_OUT_OF_MEMORY</constant>.
51 Certain other GLU functions can return specialized error codes
52 through callbacks.
53 See the <citerefentry><refentrytitle>glGetError</refentrytitle></citerefentry> reference page for the list of
54 GL error codes.
